This invention has reference generally to improvements in wrapping machines and more particularly relates to a machine for wrapping candy, filled chocolates and other kinds of confectionery. y v

It is the primary aim and object of the invention to provide a machineof the above mentioned character for applying individual wrappers or the like to a piece of candy or 1o like confectionery in such a manneras not to injure the same.

More particularly the invention lmay be said to consist in the provision of a brush die embodying a plurality of roups or bundles diustably mounted in the wall of the die or holder by securing means. so that after loosening the securin means the oups or bundles ma be a justed longitudinally, turned an rotated 20 and replaced.

lIt is an additional object of the invention to rovide improved means in the form of a rub r sleeve which surrounds each bundle of i brush-like filament, the sleeves or covers being ad'ustable longitudinally so as to deterf mine t e length of the ex osed or operating portion of the brush bund es and in t is inanner regulating the elasticity of the same. In addition the sleeves coact with the securing means so as to facilitate the pro er supporting oit the brush-like or fiber bun le.

The adjustability of the bundles in their longitudinal direction has the essential advantage that not only the pressure can regulated by this adustment but that the die may be ada ted t'o iferent shapes and sizes of pralines y the said adjustment so that in contradistinotion to the known dies of this t pe a large number of dies is not necessary.

ccording to the known machines the number of dies kept in stock must be kept in size according to the shape of the pralines to be wrapped.

Other objects aswell as the nature, characteristic features and scope of the invention will be more readily apparent from the following description taken in connection with the drawings and pointed out in the claims, forming a part of this specification.

The invention will be more particularly described by reference to the accompanying drawings showing by way of exemplification several embodiments of the principles of the invention. Fig. 1 is a longitudinal, vertical section of a die with a row of groups of hairs or the like; Fig. 2 is a top plan view of the die according to Fig. 1, and Fig. 3 is a detail showing a bundle of fibres with ,surroundin rubber rings. 4 is a modi ed form o arrangement of a die or matrice with a row of groups of hairs and' the like. Fig. 5 shows a die with a plurality of rows of such groups in vertical, longitudinal section, the several groups or brushes being horizontally arranged. Fig. 6 is a top'plan view of the die according to Fi 5 and Fig. 7 is a modified construction o a die with several rows of groups or brushes in vertical, lon itudinal section with the brushes Varrange at an incline; and Fig. 8 is a detail showing a brush employed in the modifications of Figures 5 to 7 in longitudinal section:

Uponring a and by means of the clasps b the groups, bundles or tufts of hairs or fibres c are secured, which may comprise ordinary brush fibres such as for instance badger hairs or the like. The front. ends of the bundles 'or libres are caused to be engaged with each other at d with a certain pressure, so that the bundles of fibres or hairs will surround an opening e on all sides through which the candy or other article f is forced together be with the metal foil g by meansvof a stamp or the like not shown in the drawings. As appears from Fig. 1 the several bundles c are disposed somewhat atl an inclination'on the. ring a, and in such a manner that, when the article is introduced from below the front ends are downwardly inclined, so that the free passage opening for the article f will be downwardly enlarged and the pressure of the hairs or fibres against the foil g" will become increased as a result of the insertion of the article into the die.

In view of the peculiar manner of arrangement of the bundles or brushes of fibres they mav be made adjustable with relation to each other, so that the passa e opening may be reduced or enlarged accor ing to requireall ments. It has been found to be of advantage in this connection to arrange a plurality of bundles or brushes c above each other and in such a manner that the rows are spaced from each other, the next higher row substantially admitting of the bending of the preceding row or preventing the same to a certain extent only. Rings of rubber or other elastic material may be placed around' the bundles of fibre c. By means of these rings the exposed length of the fibres is reduced -so that the touch and engagement of the ibres, as in the case of the tied painting brushes becomes harder. The length of the rings is selected in accordance with the desired degree of o eration; and a change of the action of the airs or fibres may also be produced by varying the thickness of the wall of the rings, inasmuch as the resiliency of the elastic rubber rings will be reduced in case of an increased thickness of the Wall of theelastic rubber rings.

n the case of the superimposing of a plurality of rows of brushes or groups of fibres or hairs the dilerent rows may serve in succession or the preliminary folding, plaiting, utting down, smoothening and hugging of t e foil upon the article. In the case of the superimposing of a plurality of rows each of the rows is preferably arranged 'upon a separate ring a. These rings a are secured to each other or to the frame of the machine in such a manner that the distances o the rings a from each other 'may be adjustable.

As appears rom F ig. 4 of the drawings the bundles or brushes of hairs or fibres may also be arranged in somewhat different manner with relation to each other, that is to say, so that the iront surfaces ci one kind olf' bundles cl will bear against the side suriaces of other bundles OZ it will also be seen from Fig. i that the opening which is formed or enclosed by the bundles or brushes oit bres or hairs may be shaped and cut out so as to correspond to the general shape of the article to be wrap ed.

ln the modi ed constructions according to Figs. 5 and 6 the brushes c are disposed in several rows above each other. The several brushes are arranged in openings of bisecf tional rings z', any suitable number of which may be arranged above each other so that in accordance therewith ani suitable number of rows of brushes may e provided. The

rings z' with the brushes inserted therein areconnected by means of the pressure rings la and of the screws Z inserted therein. The brushes of the superimposed rows are alternatingly disposed with relation to each other. In the form of construction according to Figs. 5 and d the brushes are arranged substantially at right angles to the center axes of' the die. In the modication accordin to Fig. 7 which in other respects 'correspon to the construction of Figs. 5 and 6, the' brushes are inclined with relation to the center axes, and in this particular case they are downwardly inclined similarly to the construction according to Fig. 1. By this means as in the case of Fig. l the result is obtained that by the insertion of the article into the die and by the upward bendingof the brushes there by produced the opening of the dies is reduced, so as to obtain in this manner a very intimate engagement of the brushes with the article and with the wrapping foil. placed around it and a very smooth" forcing of the envelope into contact with the article. The brushes employed in the orxns of construction accord-ing to Figs. 5 to 'I are of the general shape'shown in Fig. 8, that is to say, they comprise a tutt or bundle'of hairs m which is retained by a ring of sheet metal or of other material n. The free ends of the hairs or fibres are surrounded by rubber rings y h. In accordance with the length and thicknessJof wall of theserubber rings the brushes are caused to oppose a greater or smaller re; slstance against deflection, so that the pressure produced by the brushes upon the inserted article and itswrapper may be regulated at discretion by varying the sizes of these rubber rings.

In connection with the sleeves or rings it and n attention is directed to the fact that the respective bundles of bristles or line filaments o and m are connected together at their inner ends in the usual manner so as to form groups or units, the sleeves o r rings being slidable thereover toregulate the elasticity or flexibility oi the engaging portions oi the bristles of each group. In addition the inner portions and the sleeves are receivable in the clamping devices b or rings e'. In this con nection each group may be adjustably' clamped in any desired position radially of the holder b the same clamps b or 'rings z'. Moreover w en these clamping devices or rings are loosened each bundle of bristles may be rotated by hand to assume the desired position. l

I am aware that numerous details oi the construction and arrangement of parte may be varied without departing from the principles of this invention, and I therefore do not propose limiting the ambit and scope of my invention otherwise than necessitated by the a pended claims.
